Making Connections: Agriculture, Human Nutrition, and the Environment
by Vance, Laura Ivey, Ph.D., North Carolina State University, 2014, 190; 3690211
Abstract (Summary)

Plant and soil interactions are a foundation of agricultural systems, and their relationship has impacts far beyond the immediate systems. In this series of studies, we investigate how these relationships between plants and soil are connected to the environment and human nutrition.

In Chapters 1 and 2, we examine how plant/soil interactions and their management influence nitrous oxide emissions from soils. Chapter 3 examines how soil characteristics influence the potential range of an invasive species, C. benghalensis, and how this impacts eradication measures. In Chapter 4, we use a case study in indigenous Panama to investigate how soil, geography, and human factors affect nutrition of inhabitants of the Comarca Ngöbe-Buglé region, and propose ways to improve their nutritional status using the limited resources available. Finally, Chapter 5 investigates a test system for producing DHA, a nutrient found limiting in the Panama case study, using a native weed, Purslane, and laying hens.

Together, the chapters show the importance of plant and soil interactions in agriculture and the far reaching impacts of agricultural systems on the environment and human health. By understanding the relationships and interactions of different components within agriculture, we can get closer to the goal of more sustainably managed food systems.
